An interview with Dave White, a water expert at Arizona State University, about what a breakthrough along the Colorado River really means
Arizona, California, and Nevada announced a deal on Monday to reduce the amount of Colorado River water they use, ahead of a bigger overhaul planned for 2026. The agreement is crucial, likely keeping the river from reaching dangerously low levels that would have put water supplies for major cities and agricultural regions at risk. But Colorado River water policy is often knotty and confusing, and it can be difficult to wrap one’s head around just what kind of impact deals like this can have.
To that end, I called up Dave White, the director of the Global Institute of Sustainability and Innovation at Arizona State University and chair of the City of Phoenix’s Water/Wastewater Rate Advisory Committee. He explained how things work now, what the deal means, and how he’d like to see things change in the future — particularly in 2026, when the current set of water allocation rules expire and are replaced. Our conversation has been edited for length and clarity.
There are more than 100 years of law policy agreements, which we collectively call the law of the river. But the most relevant is an agreement called the 2007 Interim Operating Guidelines for the Coordinated Operations of Lake Powell and Lake Mead. That’s the long name, but we typically call it the 2007 agreement.
That agreement created a set of rules that, as the name indicates, helped to guide the operations of Lake Powell and Lake Mead. And along with subsequent agreements, particularly the drought contingency plans in 2019, it has guided the management of the reservoir system on the Colorado River and set forth the allocations managing the flow to the lower basin states.
Right now we’re in the time period between when the interim guidelines were established in 2007, updated with drought contingency plans in 2019, and when we’ll hit a deadline for a new set of operating guidelines in 2026. And so all of this is trying to manage the risk from the reduced water supply on the Colorado River and to help reestablish a balance in the supply-demand equation of water in an era of megadrought, climate change, and high agricultural demand and increasing municipal demand.
The first thing that’s important for folks to realize is that this is a proposal. What was announced was essentially an agreement among the lower basin states — California, Nevada and Arizona — to propose a plan to reduce demand in those states. It will need to go through additional steps to identify more specifics, and then this proposal ultimately will need to be adopted by the seven affected states and then endorsed by the Bureau of Reclamation.
What the proposal does is lay out a framework to reduce water demand in the lower basin by about 3 million acre feet. And for context, one acre foot is about 325,000 gallons of water, or the amount of water used by two to four homes in the western United States per year. That reduction would be taken across multiple sectors: agriculture, tribal communities, and some municipal or urban users, most notably the Metropolitan Water District of California, which is the Los Angeles area.
The idea is to reduce demand through voluntary conservation. And then part of the package is compensation for some of that voluntary conservation in the form of funding from the federal government through the Inflation Reduction Act to the tune of about $1.2 billion. That is an absolutely critical part of the of the story: the Inflation Reduction Act has really enabled this breakthrough, because of the federal funding for those voluntary conservation measures.
Another critical part of the story was that recently the Bureau of Reclamation released what’s called a draft environmental impact statement, and it presented a couple of alternatives to the states for consideration. Those proposals gave us kind of a federal government’s perspective on the framework moving forward. It was essentially a classic negotiating tactic, where the Bureau of Reclamation said, “look, you states have yet to reach a consensus agreement, so we’re going to lay out a plan,” and, as is often the case, everybody was unhappy with parts of that plan.
That helped to stimulate additional negotiations and bring California, in particular, more to the table. So it’s a very important moment in time because it represents a turning point in multi-year negotiations between the states. Importantly, it lays out a path forward for a consensus agreement that is driven by the states as opposed to being imposed upon them by the federal government. So, we’re talking about a breakthrough in negotiations that led to a three-state proposal.
Well, that’s what we’re waiting to see. We don’t have all of those details yet.
Legally, the Bureau of Reclamation needs to go through this process, weigh the different alternatives, evaluate it, identify what they would call a preferred alternative, and then ultimately make a determination. But the Bureau of Reclamation has certainly indicated there’s initial support for this proposal and that the funding would be made available.
We don’t know who specifically would receive how much of that funding but we do know that it will be agriculturalists (essentially farmers and ranchers), some municipalities such as the Metropolitan Water District of California, and some Native American communities.
We are still engaged in what I would call incremental adaptation. This is adapting to the rapidly changing conditions that are presented by this 22-year-long drought, the so-called megadrought in the region. We are also adapting to the impacts of climate change. If you go back, you know, the 2007 agreement was an incremental update to deal with a very significant risk of shortage on the Colorado River system in 2000 to 2005. We had the drought contingency planning process in 2019 that was another incremental adaptation at that time that was meant to get us to 2026, when the current guidelines expire. Environmental conditions continue to rapidly change, while the demand side continues to stay high. And while we’ve made a number of efficiency gains and voluntary reductions, the river is simply over-allocated for the flow that we have seen, especially since the turn of the millennium.
So we’ve been engaging in a series of incremental adaptations. Now, there’s nothing wrong with that. That’s a very smart strategy as you move along, right? You’re incrementally adapting your policy to reflect the changing environmental and social conditions. This is another important incremental adaptation that will hopefully allow us to keep working towards the 2026 guidelines.
What I and many others argue is that we need a more transformative adaptation, we need a more significant restructuring. Now, it’s difficult to do that right now in the midst of a very short-term risk. But eventually, between now and 2026, we need to address some of the structural imbalance, or deficit, in the river. We have over-allocated the river in this era of increasing drought and climate change.
We’ve got to restructure the demand over the course of the next several years, and that’s going to require more transformational kinds of changes. But I also want to point out that’s not limited to reducing demand, right? You can do that through dramatic increases in efficiency. We can produce the same units of product, whether that be food or microchips or homes or businesses, with significantly less water.
The most effective strategy is efficiency. It’s the cheapest. It does not require significantly new infrastructure or new water augmentation. And there are lots of good stories out there, in creating more efficiencies and creating more flexible policies and more adaptability within the way that we manage water. We’ve got to sort of wring every cool new approach we can out of the system.
One that I think is really important is that the city of Phoenix and several of its regional partners in central Arizona are in the planning stages of moving towards an advanced water-purification process. What that means is it would allow the cities to pool their wastewater resources, their effluent, and then be able to treat that water through advanced water purification so we can reuse that water for municipal use. We call that direct, potable reuse of the water.
Central Arizona is incredibly efficient, we reuse about 90% of all the wastewater that we produce in the central Arizona region for power production, for urban irrigation, for agriculture, etc. But we can actually reuse that water to support households and businesses. We can then use that water again. Some of it is consumed by people, but basically cycling the water through the city as many times as possible reduces the need for new raw water.
So the current proposal that’s in the process of being developed by the City of Phoenix Water Services Department is for advanced water purification that, according to the current estimates, would produce about 60,000 gallons of water a day for City of Phoenix residents from wastewater. And so, that’s one way we can be much more efficient in recycling and reusing our water.
I do think it gets to the need for greater public understanding and then, you know, individual and collective action. In single family residential households, for example, 50% or more, on average, of the water use is outside the home for things like residential landscaping and swimming pools. In the Phoenix area, we’ve seen a really significant trend in reducing water demand inside single family homes, thanks to technologies like low water-use toilets and more efficient washing machines and dishwashers and so on. The next frontier is getting more progressive with the way we manage residential landscaping water. And that's something that every individual household can do.
The Southern Nevada Water Authority, the Las Vegas Regional Authority, has been really at the forefront of these kinds of strategies with turf buyback programs, incentivizing homeowners, and creating all sorts of both incentives and policies to reduce that outdoor residential demand. And that’s something where individual households can be empowered.
No, I really don’t. It’s about a sort of risk management in the short term, and then crafting new policy approaches and new management strategies over the long term. So I don’t think these get in the way of each other. The 2019 agreement essentially bought us some time, and this round of proposals and anticipated agreements will continue to buy us some time.
Do I think we need more adaptation, and more significant changes? Absolutely. But I would never criticize these incremental plans, because they’re absolutely necessary to manage short-term risk.
Without these actions, there was a plausible scenario where levels in the reservoirs could drop below the minimum power pool, meaning we wouldn’t be able to create power out of the Hoover Dam. In [the Bureau of Reclamation’s] 24-month studies, we began to see scenarios in which the lake levels dropped below the intakes, meaning we wouldn’t be able to deliver Colorado River water whatsoever to the states.
When you start to see these highly undesirable scenarios where you lose the ability to produce power, you potentially even lose the ability to deliver any water at all from the Colorado system to Arizona, California, or Nevada, you know you’ve got to act and engage in short-term risk management.
The risk that we’ve always seen is that you get some relief from the kind of very strong winter precipitation in the Rocky Mountains and in California that we had this year. But as a colleague says, we cannot let one good winter take the pressure off. I never want to root against good news, and the winter precipitation and the new proposal and potential agreements are good news. But you got to keep the pressure on and keep the emphasis on the long-term strategies.
[Laughs] Yes.
Well, I think you can look at it both ways. Yes, there was the intention that the 2019 plans would get us to 2026. Turns out the 2019 plans got us through 2022. That’s just the reality we’re in. Do I wish the 2019 plans would have gotten us to 2026? Yes. But without the 2019 plans, we would have been at risk of minimum power pool levels even earlier.
I was hopeful the 2007 plans would get us to 2026. But the reality is that the climate is changing, the drought has just been incredibly persistent. I mean, we now know from looking at reconstructions of the past climate that this 22-year period is the driest period in our region in the last 800 years for certain, and very likely in the last 1,200 years. That’s an exceptional period of drought. And so, by some measures, you know, it’s pretty remarkable what the water management community has done to manage the risk without significant disruption to the region. So in some ways, it’s a success story.
The single most important thing everyone recognizes is that we really need to chart a new path forward for agriculture. Particularly for agriculture in the lower basin, and even more specifically for non-food forage crops in the lower basin.
We still use two-thirds or more of our water in the lower basin for agriculture, and most of that is used for forage crops, like alfalfa, which feed livestock. So we very much need to restructure the agricultural sector in the lower basin and think about prioritization of certain types of agriculture in certain locations. And importantly, we need to work with agricultural communities, with landowners and businesses, to help them transition to a future that recognizes there’s less water available. And, you know, this is the challenge that we face: How do we make an intentional, thoughtful, supportive transition to a new, more efficient, and more appropriate type of agriculture in the West?
This region is in an amazing region to grow alfalfa if you have water. And so, there’s lots of rational choices that were made along the way. But in an era of significantly reduced water availability, it is simply not sustainable for us to continue to use that much of our available water for agriculture, and in particular for forage crops mostly to support cattle. And so this has to change.
I fully recognize, though, that these are private property rights, and there needs to be a process for this. We can’t just simply have a situation like what we saw in the Midwest where we just move all of our manufacturing overseas and abandon entire swaths of the country. We have to think about how we can help, whether it’s through compensation, community planning, capacity building, job transitions, etc. But that’s the biggest part of the solution. We need to be very thoughtful about that.
I think one of the key things we really need to get into the planning process [for 2026] is greater adaptability and greater flexibility so we’re able to respond to changing conditions. Under the current guidelines there is a priority rights process where we would have [hypothetically] seen the reduction of essentially all — 100% — of Arizona’s allocation of the Colorado River, before any of California’s rights were reduced. But it seems implausible to eliminate the Colorado River water supply to Phoenix, which is the fifth largest city in the country. These are the third rails of water politics. We have to rethink the way that these water allocation decisions are made, and we’ve got to be much more flexible, much more adaptable, and really think about how we can respond to climate and water conditions.

On the Greenhouse Gas Reduction Fund, Canada’s new prime minister, and CERAWeek
Current conditions: Firefighters successfully controlled brush fires in Long Island that prompted New York Gov. Kathy Hochul to declare a state of emergency • Brisbane, Australia, recorded its wettest day in more than 50 years • Forecasters are keeping an eye on a storm system developing across the central U.S. that could pack a serious punch this week.
The nonprofit Climate United filed a lawsuit over the weekend against the Environmental Protection Agency and Citibank for withholding $7 billion in climate funds awarded as part of the Biden administration’s Inflation Reduction Act. The move escalates a dispute over some $20 billion in grants from the IRA’s Greenhouse Gas Reduction Fund, which was designed to help mobilize private capital toward clean energy and climate solutions. President Trump’s EPA Administrator Lee Zeldin has been on a mission to claw back the funds, claiming their distribution was rushed and mismanaged. In its lawsuit, Climate United says it has been unable to access the $7 billion it was awarded, and that the EPA and Citibank have given no explanation for this. It wants a judge to order that the money be released. “We’re not trying to make a political statement here,” Beth Bafford, chief executive of Climate United, toldThe New York Times. “This is about math for homeowners, for truck drivers, for public schools — we know that accessing clean energy saves them money that they can use on far more important things.” The Trump administration has reportedly demanded that the eight organizations tapped to receive the money turn over records to the FBI and appear in federal court later this month.
Canada’s Liberal Party has elected Mark Carney, a net-zero finance advocate, to succeed Justin Trudeau as prime minister. Carney is not a career politician. Instead, he comes from the financial world, having overseen both the Bank of Canada and the Bank of England, and is an evangelist for green investment and a net-zero financial sector. He was the UN Special Envoy for Climate Action and Finance in 2019, and “has made clean energy, climate policies and economic prosperity for Canada some of the central facets of his campaign,” CNN reported. If he wins the upcoming general election, Carney will be tasked with navigating President Trump’s tariffs and making key decisions about the future of Canada’s vast natural resources, including fossil fuels and rare minerals.
The U.S. has withdrawn from yet another global climate initiative, this one aimed at helping developing nations recover from natural disasters. The United Nations loss and damage fund was one of the biggest wins to come out of COP28 in 2023, with nearly 200 countries signing on in support. It’s expected to start funding projects this year. About $740 million has been pledged so far, and the U.S. has said it will give about $17.5 million, though it’s unclear if that money will actually be handed over now. “This decision, made by the nation with the largest historical responsibility for climate change, jeopardises vital support for vulnerable countries facing irreversible climate impacts,” said Ali Mohamed, the chair of the African Group of Negotiators.
The energy industry descends on Houston, Texas, this week, for the annual CERAWeek conference. This year’s event, titled “Moving Ahead: Energy Strategies for a Complex World,” will focus on the changing global energy landscape. Key themes include shifting regulations, the turbulent oil and gas market, electrification and power demand, the rise of AI, managing emissions, and the policy outlook for renewables. According toReuters energy columnist Ron Bousso, fossil fuel executives are going into the conference with a case of “Trump buyer’s remorse” as new tariffs and geopolitical policies from the Trump administration have “created turmoil in financial markets and clouded the outlook for the global economy and energy prices.”
Argentina will observe three days of national mourning after 16 people were killed in flash flooding over the weekend triggered by unprecedented rainfall. Nearly a year’s worth of rain – about 16 inches – fell in just eight hours in the port city of Bahia Blanca in the Buenos Aires province. Many people are still missing. Environment official Andrea Dufourg said the event was a clear example of climate change. “Unfortunately this will continue to take place,” Dufourg said. “We have no other option than to prepare cities, educate citizens, and establish effective early warning systems.”
Twenty-one House Republicans have signed a letter urging the GOP to uphold the Inflation Reduction Act’s clean energy tax credits in their budget bill, warning that gutting the credits would “risk sparking an energy crisis in our country, resulting in drastically higher power bills for American families.” That’s three more than signed a similar letter during the last Congress.
While they’re getting more accurate all the time, they still rely on data from traditional models — and possibly always will.
The National Oceanic and Atmospheric Administration has had a bruising few weeks. Deep staffing cuts at the hands of Elon Musk’s efficiency crusaders have led to concerns regarding the potential closure of facilities critical to data-gathering and weather-forecasting operations. Meteorologists have warned that this could put lives at risk, while industries that rely on trustworthy, publicly available weather data — from insurance to fishing, shipping, and agriculture — are bracing for impact. While reliable numbers are difficult to come by, the agency appears to have lost on the order of 7% to 10% of its workforce, or more than 1,000 employees. NOAA’s former deputy director, Andrew Rosenberg, wrote that Musk plans to lay off 50% of the agency, while slashing its budget by 30%.
Will that actually happen? Who the heck knows. But what we can look at are the small cracks that are already emerging, and who could step in to fill that void.
One thing that’s certain is that the National Weather Service, a division of NOAA, announced last week that it is suspending operations at a weather balloon launch site in Alaska, due to staffing shortages. The data gathered at this remote outpost helped inform the agency’s weather forecasts, which are relied upon by hundreds of millions of people, as well as many of the world’s largest companies and public agencies.
Perhaps to Musk’s department, this looks like a prime opportunity for the private sector to step up and demonstrate some nimble data gathering prowess — and indeed a startup that I’ve covered before, WindBorne, has already offered its services. The company, which makes advanced weather balloons, has offered to provide NOAA with data from its own Alaska launches for six months, at no cost. WindBorne is also one of a number of private companies creating AI-based weather models that have outperformed NOAA’s traditional, physics-based models on key metrics such as temperature, wind speed and direction, precipitation, humidity, and pressure.
All this raises the question, though, of what kind of role the private sector could and should play in the weather forecasting space overall. If the architects of Project 2025 have their way, NOAA would be “broken up and downsized,” and its National Weather Service division would “fully commercialize its forecasting operations.” If the Trump administration achieves these goals, “the Weather Service would cease to function in a way that it could meet its mandate to protect American life and property,” Daniel Swain, a climate scientist at University of California Agriculture and Natural Resources, told me.
But given that heavyweights like Google, Huawei, and Nvidia are already in the AI-based weather prediction game, along with startups such as WindBorne and Brightband, which is making weather predictions tailored to the needs of specific industries such as insurance, agriculture, or transportation, it wasn’t clear to me whether, if NOAA were to crumble, the accuracy of weather forecasts necessarily would, too. I thought that perhaps Musk, the White House’s most notorious AI enthusiast, might be thinking the same thing. So I asked around.
“There’s actually a very good argument that I think would be very uncontroversial to expand the role of the private sector, even to offload certain parts of the workflow to the private sector,” Swain told me, with regards to NOAA and its adoption — or lack thereof — of AI-based weather forecasting. But what nobody wanted was to get rid of free, publicly available government forecasts completely.
“I don’t want to have to figure out what company to trust. I just want to be able to go and open the National Weather Service and know what’s going on,” John Dean, the CEO and co-founder of WindBorne, told me.
Julian Green, the CEO and co-founder of Brightband, agreed. “The government doesn’t just forecast the weather, but it gives people alerts. And there’s regulation around whether [it tells you that] you should evacuate, or shut your factory down, or so on.” It’s not hard to imagine the ethical quandaries that could arise from a private company with a profit motive deciding who can access potentially life-saving forecasts, and for how much.
WindBorne’s and Brightband’s AI models, as well as those from tech giants such as Google, are significantly less computationally intensive to operate than those from NOAA or the other leading weather forecasting agency, the European Center for Medium-Range Weather Forecasts. These traditional models rely on supercomputers crunching complicated atmospheric equations based on the laws of physics to make their predictions.
But this doesn’t mean the physics-based models are getting replaced by AI now, or potentially ever. Government data and traditional forecasts still make up the backbone of advanced AIs, which are trained on decades of data largely gathered by NOAA satellites, weather balloons, and radar systems, and then interpreted through the lens of standard physics-based models. After training is complete, the AI models can predict what weather patterns will develop, much like ChatGPT predicts the next word in a sequence, but only after being fed a snapshot of initial weather conditions — also pulled from traditional physics-based models.
Essentially, these AI forecasts are built on the backs of the giants, and while their outcomes are hugely promising, they could not exist without that solid foundation. While one day, it might be possible to operate AI forecasting models without relying on traditional models, Dean and Green told me that physics-based models might always be critical for training the AI. So while their companies’ respective models have yielded impressive results, both Dean and Green nixed the idea that their companies could wholly replace the predictions made by the National Weather Service.
All of this is in flux of course, but as Green put it to me in an email, “a good mechanic doesn't throw away good older tools just because you get new tools.” Plus, as Dean explained, there are still conditions under which physics-based models tend to outperform AI, such as “really small-scale and high-res phenomena — let’s say convective events, let’s say severe thunderstorms in the Plains, or tornado formation.”
Even Project 2025’s authors point out that private industry forecasters rely on publicly available NOAA data, though it doesn’t make any reference to AI models or physics models. The document simply says that the agency “should focus on its data-gathering services” and the “efficient delivery of accurate, timely, and unbiased data to the public and to the private sector.”
There are also questions around whether AI models, trained on data from the past, will be able to predict the types of unusual and extreme weather events that are becoming more and more common in a warming world, Swain told me. “Does it fully capture those?” he asked. “There’s a lot of evidence that the answer is no.”
Lastly, NOAA’s weather model, the Global Forecast System, is simply measuring much more than the AI models do today. “It predicts so many different phenomena, like different types of snow, hail, mixing ratios, turbulence,” Dean said. “We’re building up over time to add more and more variables. But for both WindBorne and other models, it’s not the same currently as what GFS does.”
So while the Heritage Foundation might want to delegate all forecasting responsibilities to private companies, the vision I heard from the startups I talked to looked more like a mutually beneficial arrangement than the full commercialization of weather prediction, or even a clean division of labor. “It’s not privatized weather, it’s a public-private partnership,” Dean said of his ideal future, “where you get freely available forecasts from a public institution like NOAA, but they work with our industry to iterate faster and to drive more innovation.”
What everyone seems to want is simply for the government to forecast better, and today that means moving quickly to build AI-based models. NOAA has taken some steps forward, prototyping some models, bolstering its computing capabilities, and even recently partnering with Brightband to optimize its observational data to train AI models. But it remains behind other agencies in this regard. “The Chinese government and the European Center for Medium Range Weather Forecasts have done a far better job at adopting AI-based weather forecasts than NOAA has,” Dean told me. “So something does need to change at NOAA to get them to move faster.”
Indiscriminately laying off hundreds of the agency’s employees may not be the best place to start. But if there’s anything we know Musk loves, it’s AI and private sector ingenuity. So maybe, just maybe, this administration will be able to forge the kind of partnerships that can supercharge federal forecasting, while keeping NOAA’s weather predictions free and open for all. Or maybe we’ll all just be paying the big bucks to figure out when a hurricane is going to hit.
On energy transition funds, disappearing butterflies, and Tesla’s stock slump
Current conditions: Australians have been told to prepare for the worst ahead of Cyclone Alfred, and 100,000 people are already without power • Argentina’s Buenos Aires province has been hit by deadly flooding • Critical fire conditions will persist across much of west Texas through Saturday.
Many foreign aid programs have reportedly received a questionnaire from the Trump administration that they must complete as part of a review, presumably to help the government decide whether or not the groups should receive any more federal funds. One of the questions on the list, according toThe New York Times, is: “Can you confirm this is not a climate or ‘environmental justice’ project or include such elements?” Another asks if the project will “directly impact efforts to strengthen U.S. supply chains or secure rare earth minerals?” President Trump issued an executive order freezing foreign aid on his first day back in office. The Supreme Court subsequently ruled that aid must be released. The Times notes that “many of the projects under scrutiny have already fired their staff and closed their doors, because they have received no federal funds since the review process ostensibly began. … Within some organizations, there are no staff members left to complete the survey.”
The United States has withdrawn from a global financing program aimed at helping poorer nations ditch fossil fuels and shift to clean energy. A spokesperson from the Treasury Department said the Just Energy Transition Partnership does not align with President Trump’s vision of American economic and environmental values. The program was launched in 2021 and has 10 donor nations, including many European countries. Its first beneficiaries were Indonesia, Senegal, South Africa, and Vietnam. The U.S. had committed more than $3 billion to Indonesia and Vietnam and nearly $2 billion to South Africa under the initiative. “The U.S. withdrawal is regrettable,” said Rachel Kyte, the U.K.’s climate envoy. “The rest of the world moves on.” In January, the Trump administration canceled $4 billion in pledges to the Green Climate Fund. “We have to plan for a world where the U.S. is not transfusing funds into the green transition,” Kyte added.
Butterfly populations in the U.S. are rapidly declining due to a combination of climate change, habitat loss, and pesticide exposure, according to a “catastrophic and saddening” new study published in the journal Science. “Butterflies are vanishing from the face of the earth,” one of the study’s co-authors told The Washington Post. The research analyzed data from 77,000 butterfly surveys and found that butterfly numbers have fallen by 22% in just 20 years across the entire country. Of the 342 butterfly species that could be analyzed for trends, 107 plummeted by more than 50% and 22 by more than 90%. Just nine species saw their numbers rise. The researchers say these numbers are likely an underestimate.
The findings underscore the crisis facing all the small, underappreciated insects that pollinate flowers and crops, control pests, maintain soil health, and play a vital role in the food chain. According to the World Wildlife Fund, up to 40% of the world’s insect species may disappear by the end of the century. The study’s lead author, ecologist Collin Edwards, said there is some hope. “Butterflies have fast life cycles,” he said. “At least one generation per year, often two or three. And each of those generations lays a ton of eggs. This means that if we make the world a more hospitable place for butterflies, butterfly species have the capacity to respond very quickly and take advantage of all our efforts.”
The Government Accountability Office yesterday said that Congress can’t review (or repeal) the Environmental Protection Agency’s waiver that lets California set its own vehicle emissions standards. The decision derails plans being spearheaded by Republicans and EPA Administrator Lee Zeldin to use the congressional review process to overturn the waiver. California’s aggressive emissions standards, which have been adopted by many other states, would effectively end the sale of fully gas-powered cars by 2035. Republicans are mulling their next move.
Tesla’s stock price has been taking a beating as resentment grows around CEO Elon Musk’s political meddling. The company’s valuation soared from around $800 billion to $1.5 trillion in December, when it became clear Musk would become the president-elect’s right hand man. Since that moment, the company’s value has fallen by more than $600 million, effectively erasing the bump in Tesla’s market cap. Shares fell by 5.6% yesterday alone, and sales are cratering abroad and in key U.S. markets like California.
As Andrew Moseman explains for Heatmap, a big drop in sales could be a double-whammy for Tesla revenue. “Recall that the company’s most reliable revenue stream is not really its sales of electric cars, but rather the carbon credits generated by those EVs under California’s auto emissions regulatory scheme, which it can sell to other automakers who’ve yet to meet their emissions targets,” Moseman says. “Tesla’s tumbling sales in the wake of Musk’s antics could reduce the amount of credits it could sell to others, since the credits are tied to sales of low-emissions vehicles.” There was more bad news for Musk today: A SpaceX Starship rocket exploded during a test flight, sending flaming debris flying across a large area and disrupting air traffic in Florida.
A new report shows that a year after London expanded its low-emissions zone, air quality in the city has improved, with nitrogen dioxide levels across 2024 down significantly:
